CUTTING-MACHINE- SPECIFICATION forming part of Letters Patent No.768,629, dated August 30, 1904-.

' Application filed December 10, 1903. Serial No.1s4,517. (1 model-) To(all whom, it may concern.-

Be it known that 1, ALBERT E. SCHUOHERT, a citizen of the United States,residing at Oincinnati, in the county of Hamilton and State from thefollowing description and claims and from the drawings, in which latter-Figure l is a side elevation of my improveddevice with the table andcutting-frame shown in full lines in normal position, the cuttingframebeing also shown in depressedposition and the table in tilted positionin dottedflines. Fig. 2 is a'plan view of my-improved device, partly insection, Fig. 3 is a perspective view of one of the. table-sections.Fig. 4 is a detail, partly in section, showing the means for connectingthe table-sections for assembling the combined table. Fig. 5 is a detailin cross-section, showing the means for stretching or tautening thecutters; and Fig. 6 is a cross-section on the line a a; of Fig 2-,showing the construction of the frame. I

A represents the main frame,'which may comprise the sides a a and thecross-girt (f.

B is the table, and O the cutting-frame.

The main frame A has bearings l 1,in which the cross-shaft 2 of thecutting-frame is journaled. The cutting-frame, in the form shown,-comprises the cross-shaft 2, a cross-bar 3, and sides 4 5, connectingthe cross-shaft and crossbar. Each end of the cross-shaft and thecross-bar is reduced, as shown at 6, forming a shoulder 7, against whichthe side takes, a nut 8 screwing over the reduced end and clamping theside in place against the'shoul as wires) and connected to hooks 12presented downwardly on bolts 13 in-the cross-shaft andcrossbar,respectively, nuts 15 taking over the threaded ends of thebolts and against the cross-shaft and cross-bar, respectively, for

tautening the cutters. The bolts respectively slide in'apertures 17 inthe cross-shaft and cross-bar, respectively. The cutter-frame hashandles 19 20and is provided with a bolt 21, taking into an aperture 22in the are 23 on the frame for normally keeping the cutter-frame inraised position, a spring 24 urging the bolt normally into the aperture22, a finger 25 beeach of which has hubs 31 32, respectively,

through the openings 33, with washers 36 taking between adjacenttable-sections for separating thesections just suificiently forprovidingthespace orslo'ts 29 between the edges of adjacenttable-sections in which the cutters 9,

may reciprocate. The shaft isthreaded adjacent to its ends, as shown at30, nuts 37' taking over said ends and clamping the washers and tablesections together on the shaft.

. Each end of the shaft has a journal 38 journ'aled in a bearing 39 inthe reduced forward end L0, at each side of .themainiframe, the shaftrocking in the bearing when the table is .tilted. A'rod 451 takesthrough the openings 34:, washers similar tothe washers 36 being placedbetween adjacent table-sections. I The 1 rod 4L1 may be in the form of abolt with a nut 42 clamping the table -'sections and washers between thehead 430i the'bolt and the nut.

In this manner a combined table of simple and cheap constructionprovided with the necessary slots for the cutters isformed and a tableprovided in which the width of the slots may be determined by thethickness of the The table is preferablycomposed of a number of sectionsD,

having openings 33 34. Ashaft 35 takes washers used, dependent on thethickness of the wire or other cutter it is desired to employ, which inturn is dependent on the material to be cut.

Each table-section preferably comprises the hubs 31 32 and preferably abed 46 and back 47, the bed and back being thin at their edges, thesection being strengthened by webs 48. The bed and back of thetable-sections being thin at their edges, it requires little traversingof the cutters at any given point across the same before the cuttershave passed said edges, and they also present little side surface uponwhich any of the material being cut may cling. It also permits thecutting edges of the cutters to pass beyond the said edges of thetable-slots when cutting the material, as indicated by the dotted lineof the cutter shown in Fig. 1, and into the spaces Z) between the webs,which spaces present clearance beyond the thin edges mentioned under thebed and to rear of the back for permitting such portions of the softmaterial operated on which may be removed by the action of the cuttersto drop without clogging the cutter slots. The frame is also preferablyunobstructed under the table, the table normally resting on lugs 49 50,extending from the frame, the lugs preferably extending only under theend sections of the table for providing clearance under the table forconvenience in removing the waste particles of material that may beforced through the spaces between adjacent cutters. As shown, the endsections of the table may be narrow for cutting off the butt, heel, orwaste end of the material. The table-sections are provided withindentations 51, adapted to take over the cross bar 3 when thecutterframe is lowered and the table tilted for permitting the materialwhich has been cut to drop therefrom onto a board or into a receptaclethat may be provided for the purpose, the tilting of the table providinga convenient way for removing the cut material therefrom without thenecessity of touching the material. When it is in its lowered position,the cutter frame rests on a lug 52 on the main frame.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

1. In a cutting-machine, the combination of a table having a series ofslots and clearance-spaces for said slots wider than said slots, undersaid slots, and a cutter-frame, with a series of cutters on saidcutter-frame taking into said slots from above, said slots merging intosaid clearance-spaces.

2. In a cutting-machine, the combination of a table having a series ofslots and clearance-spaces for said slots wider than said slots undersaid slots, and a cutter-frame, with a series of cutters on saidcutter-frame taking into said slots from above, constructed and arrangedfor permitting the cutting edges on said cutters to take through saidslots and into said clearance-spaces under said slots, and means foradjustably tautening said cutters.

3. In a cutting-machine, the combination of a table-frame composed of aseries of sections rigidly secured together, the adjacent edges of saidsections being spaced apart to form aseries of slots in the table-frame,means for securing said table-sections rigidly together for forming arigid unitary table, a cutter-frame, and cutters therefor arranged totake into said slots so formed.
